CD74 Fault - Fault Reads - Motor Speed Exeeded

Any ideas out there on how to overcome this fault. On a red so cannot turnover press.
Have switched press on/off. But fault still appears??????????
Help please.

 

Check your drive belt, make sure it is free of oil. What is the error code that shows up?

 

This usually happens when you run out of coating or water, and usually re-booting the press works, sorry I am not more help.

 

weird, usually rebooting works , is there a number like when its a guard or something? good luck....

 

Could also be a bad coater clutch. Does it happen even when not using the coater?

 

Hi there.

Can anyone help

Does the error appear on more than one unit?
